phytoplankton community production, size export of large aggregates: A world-ocean
2014/4/17
We recorded vertical profiles of size distributions of large particles (.100mm) to a 1000-m depth in the Atlantic, Indian, and Pacific Oceans and in the Mediterranean Sea with theUnderwater Video Prof...
Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Evidence of warming effects on phytoplankton productivity rates and their dependence on eutrophication status
warming effects phytoplankton productivity rates eutrophication status
2014/4/17
Using 31-yr data from measurements in a lake that has experienced change in eutrophication status, I showed that the effects of global warming on chlorophyll a (Chl a)–normalized maximum rates of phot...
Environmental control of open-ocean phytoplankton groups: Now and in the future
Environmental control open-ocean phytoplankton groups Now and in the future

Climate change will alter concurrently many environmental factors that exert control over oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field surveys reveal many re...
Effect of a flood event on the dynamics of phytoplankton and biogeochemistry in a large temperate Australian lagoon
a flood event on the dynamics phytoplankton biogeochemistry temperate Australian lagoon
2014/4/17
In episodically driven estuaries, nutrient delivery is typically confined to sporadic flow events, followed by intense biogeochemical recycling of nutrients. We document the response of a temperate la...
How anthropogenic darkening of Lake Apopka induced benthic light limitation and forced the shift from macrophyte to phytoplankton dominance
Lake Apopka induced benthic light limitation forced the shift macrophyte to phytoplankton dominance
2014/4/17
Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka,a shallow, 125-km2lake in central Florida, U.S.A. The controversial questions are: was a lake-...
Can photoinhibition control phytoplankton abundance in deeply mixed water columns of the Southern Ocean?
photoinhibition control phytoplankton abundance deeply mixed water columns the Southern Ocean
2014/4/17
To study how natural Southern Ocean phytoplankton communities acclimate to rapid fluctuations in irradiance levels that result from deep wind-driven mixing of the upper water column, we measured their...
A model of phytoplankton acclimation to iron–light colimitation
phytoplankton acclimation iron–light colimitation
2014/4/16
We developed and calibrated a dynamic model for cellular carbon, chlorophyll (Chl), and iron under iron–light
colimitation. The model allows growth rate and two other state variables (Fep
